As technology continues to advance, it is evident that the internet is becoming more essential than ever before. That's why professionals in the tech industry continue to develop and research ways to improve it. One of these improvements is the transition to Internet Protocol version 6 (IPv6). IPv6 has been in development for decades, yet its worldwide implementation still seems to be a slow process. So, when is IPv6 going to replace IPv4? This article will delve into the specifics of the transition and discuss what to expect.

IPv6 was designed to replace Internet Protocol version 4 (IPv4) mainly for two reasons. The first reason is that the number of IPv4 addresses was quickly running out, given the explosive growth of devices requiring an IP address. Secondly, the design of IPv4 was becoming outdated, presenting many limitations for modern internet capabilities. The deployment of IPv6 can support new features such as better quality of service, authentication, and security for IoT networks, and massive address space.

The implementation of IPv6 worldwide continues to take place. However, it is not an overnight process as it requires support from internet service providers (ISPs), hardware manufacturers, and other entities. The migration to IPv6 is in progress, and its utilization continues to increase. Although the pace is slow, the trend is positive. Many countries have already made significant progress in adopting IPv6.

The delay in the IPv6 transition can be attributed to a lack of understanding of the benefits it presents, lack of appropriate funds to upgrade systems, and incompatibility of its infrastructure with IPv4. Some large organizations still rely heavily on legacy systems that operate on IPv4, and the migration to IPv6 may require a complete overhaul of their operating systems. Another barrier to the transition to IPv6 is the lack of a strong incentive for all parties involved in a system to migrate to IPv6. Some businesses do not see the need to upgrade their systems if they can still function optimally and secure a connection with IPv4.


IPv6 hasn't fully replaced IPv4 yet, but it is well-positioned as the future of the internet's development. The transition to IPv6 needs more advocacy, funding, education, and technological investments. More devices are being made to support IPv6, and the usability between the two protocols is being made seamless. As seemingly more devices depend on the internet each day, it is crucial to adopt IPv6 to promote scalability and security.
